Specification of Letters Patent.

Application filed September 29, 1913.

To (ZZZ whom it may concern:

Be it known that we, MAGNUS GUsrArsoN and Tnnononn Swanson, ubjects of the King of Sweden, residing at Duluth, in the county of St. Louis and State of Minnesota, United States of America, have invented certain new and useful Improvements in Swamp- Horseshoes, of which the following is a specification, reference being had therein to the accompanying drawing.

Our invention relates to improvements in swamp horseshoes.

The object of our invention is to provide a shoe of this character which is simple in construction, readily applied and designed to be used in connection with the usual iron horseshoe.

Another object of our invention is to provide a shoe of this character which is made of wood, giving a greater bearing surface and preventing the same from sinking deep into snow or soft ground for which our device is more especially adapted.

A still further object of our invention is to provide a shoe that is readily adjusted to fit any sized hoof and which can be readily applied and removed.

In the accompanying drawingFigure 1 is a to plan view of our improved swamp shoe. Fig. 2 is a side elevation of Fig. 1. Fig. 3 is an enlarged perspective view of a toe clamp. Fig. & is a plan view of the plate attached to the under side of the front of the wooden shoe and to which the toeclamp is secured and to which the front calk is also attached. Fig. 5 is a perspective view of the rear heel calk.

Referring now to the drawings, 1 represents the main body portion of our improved shoe which is preferably made of wood, but, as is understood, could be made of any other material. This body-portion is made considerably larger than the ordinary horseshoe and of sufficient thickness to withstand the ordinary usage. It is understood that our improved shoe is adapted to be applied to the hoof over the ordinary iron shoe and in order that the body-portion may be read ily clamped to the iron shoe, we provide the forward end of the body-portion 1 with the vertical elongated slot 2. The body portion being preferably made of wood, it is essential to provide the same with a plate 3 surrounding the opening 2 and having its forward end 4: bent downwardly into the recess 5 in the upper face of the body-portion. The lower face of the body-portion 1, surrounding the slot 2, is provided with a recess 6, in which is placed a plate 7, which has its forward end 8 bent downward flush with the lower face of the body-portion. It is understood that both plates 3 and 7 are provided with slots corresponding to the slot 2 of the bodyportion. Passing upwardly through the downwardly turned portions 4: and 8 of the plates 3 and 7, is the forward calk 9, which is secured thereto by means of a nut 10, which is screwed on the upper end of the calk and rests wholly within the recess 5, in the forward end of the body-portion. In order that the iron horseshoe carried by the hoof may be firmly held against backward movement, we provide a clamp 11, which extends downwardly through the slot 2 in the body-portion and through the slots in the plates 3 and 7 and is held in its adjusted position against the back edge of the horseshoe by means of a nut 12, which is wholly within the recess 6 in the lower face of the body of the shoe. The clamp 11 passes through an elongated slot 13 in the movable bar 14 and is secured by the nut 12; it will be seen that the clamp 11 can be moved on the face of the bar 14: to fit shoes of different widths.

The rear end of the bodyportion 1 is provided with a transverse elongated recess 15 in which is embedded the plate 16 and the lower face of the body portion below the plate 16 has a. plate 17 set therein, the outer face of which is flush with the body of the shoe. Passing upwardly through the plates 16 and 17 are the rear calks 19, which are secured to the body-portion of the shoe by means of nuts 20, which are wholly embedded in the recess 15 in the rear end of the body-portion of the shoe.

The body-portion of the shoe, as heretofore stated, is preferably made of wood, but can be made of any other desired material. Approximately midway the ends of the said body-portion adjacent the sides are slots 21 and 22, in which rest the eyes 23 and 24;, which are pivotally secured within the slots by means of bolts 25. Pivoted upon the eye 24 is a bar 25 of a curved form to fit that of the hoof of the animal to which the device is to be applied and which is provided with a series of openings 26, the object of which will be hereinafter more fully described. A loop 27 is provided with a hooked end 28, adapted to pass through any of the open- This thumb screw 33 is carriedby the plate 29 and by the structure just described it will be seen that the'locking lever 31 is held in the position shownin Fig. 1 of the drawing.

In order to'prevent any chafing of the hoof, we provide a leather pad 34, which extends under the loop 27 and plate 29, be-

tween the same and the hoof, so that the loop 27 and the hoof.

From the foregoing description it will be readily seen that we have provided a swamp shoe which can be readily applied to the hoof and the clamp 11 prevents any rearward movement of the shoe on the hoof and the locking lever and its cooperating" parts prevent the rearward movement of the plate 29 do not directly engage shoe on the hoof.

Having thus described our im'ention what we claim and desire to secure by Letters Patent is:

A shoe of the character described, having a broad flat sole, calks secured to the said sole, the said sole adjacent the rear end on opposite sides having vertical recesses, eyes pivotally mounted within said recesses, a plate pivotally mounted upon one of said eyes and having a plurality of openings, a loop having a hooked end adapted to enter one of the said openings, a plate pivotally carried by the opposite end of the loop, a locking lever pivotally carried by the opposite end of the plate, and passing through the eye on the opposite side of the shoe, and a thumb screw for holding the lever in its locked position.

In testimony whereof we hereunto aflix our signatures in the presence of two witnesses.

Witnesses A. C. DUNN, C. Gr. SoHUL'rE.
